Title: Unable to open FRED mission
Post by: Colt on July 17, 2019, 03:17:18 pm

So I was doing some editing, but when I went to save the mission, I got an error about some sexp expressions (this usually happens when inserting new events between other events). Whenever this happens I just press continue and then proceed to fix them. This time however I got the following error.

Code: [Select]

Error: Failed attempting to reload mission after saving.  Report this bug now!

Every time I try to load the mission in FRED I get a window that says it is unable to load the mission file. How would I go about fixing this?

Can have a wide range of causes. IIRC running a debug built _might_ be able to bring you to the point where it happens, not 100% sure.

-You forgot a space after an event name ("Destroy Gemini ")
-Change hierarchy of events so "is-event-true-delay" will show <Gemini Event>

basically everything that throws out a error (apart from the usual GTF Ship 0 not part of wing stuff) can cause FRED to refuse to load your mission nowadays.

Yep that's what it was.

Also I remembered that I could edit the mission via a text file  :banghead:. All's working now!

Be super careful with that, 1 typo and you've got a good chance to end up in the same issue again.

Pfff... Real Freders use notepad!

Confirmed that sexps with illegal entries (bad hangar bay assignments, ships that don't actually exist, etc.) cause FRED to treat a mission as entirely corrupted rather than spit out a list of the errors in the mission like normal. I'm working on a Github issue now.

Yeah, the game should at least spit out what might be the cause even if it can't load the mission.

Yikes. Gonna be super careful for the time being. Thanks for finding that.

Possible fix submitted. Next nightly (not today's) will probably have it.  Until then, you can try editing any bad sexp in notepad.
